Abstract
The coupling constant of the meson vertex J/ÏDsDs is calculated using the three point correlation function within the QCD sum rules formalism. We have considered alternately mesons J/Ï and Ds off-shell together with non-perturbative contributions up to the mixed quark-gluon condensates. When extrapolated, these two different form factors give the same coupling constant for the process gJ/ÏDsDs=5.98â0.58+0.67.
